Clapper: ISIS can stage Europe-style attacks in U.S. – CNN.com

ISIS has the capability to stage a Paris-style attack in the U.S. using local cells to strike in multiple locations and inflict dozens of casualties, according to the Obama administration’s top U.S. intelligence official.

“They do have that capacity,” Director of National Intelligence James Clapper told CNN’s Peter Bergen in an exclusive interviews on “AC 360” on terrorism, Osama bin Laden and al Qaeda’s most virulent offshoot — ISIS.
